[Radiance-general] Using variables and maths functions in .rad files

[Michael Bannert]

ah, of course! i remember that being mentioned in the tutorial :) that might actually do all of the tasks that i had in mind because that command - as i understand it - can be called from within a bash script where i can define the geometric layout in more abstract terms.
thank you!
